PhD, MPH Lack of physicaJ activity is closely linked with the incidence of several chronic di.seases and a lower quality of life.'”^ There is now an array of physical activity interventions that have been proven to be effective acnass a variety of populations and geographic settings. For example, the Task Force on Community Preventive Services has prodticed a set of evidence-based guidelines for promoting physical activity tided Vie Guide to Community Preventive Services: iVhat Works lo Promote Health? (hereafter Community Guide).^”^ In the Community Guide, intervention strategies that show evidence of increased physical activity in targeted populations art’ grouped into 3 categories: (1) informadonal approaches to change the knowledge and attitudes regarding the benefits of and opportunities for physical activity within a community among pnpulations that state and local public health workers serve; (2} behavioral and social approaches to teach the targeted populations tbe behavioral management skills necessary for successftil adoption and maintenance of behavior change and for creating sodal environments that facilitate and enhance behavioral change; and (3) environmental and polic>’ approaches to change the structure of physical and organizational environments to provide sate, attractive, and convenient places for physical activity. Across these 3 categories, 8 specific intervention strategies were foimd to have sufficient or strong evidence of effectivenes.s.”” Effective intervention strategies, such as those in the Community Guide, can be implemented in community settings through the etTorts of nttmeroits agencies, organizations, and individuals.
